Under legislation signed by former President Obama on Dec. 19, the state will then transfer the remains to Native American tribes that have fought for two decades to reclaim and rebury what they consider to be an honored ancestor.

Gaskill said she doesn’t know if that transfer will take place Friday. Representatives of the state arachaeology department could not be immediately reached.

Chuck Sams, spokesman for the Confederated Tribes of the Umatilla Indian Reservation, has said the reburial will be private.

The federal legislation specifies that the transfer must take place within 90 days of the bill’s enactment.

Unearthed from the banks of the Columbia River in 1996, the bones comprise one of the oldest and most complete human skeletons ever discovered in North America. The find set off a bitter legal battle between scientists who wanted to study the remains and local tribes who wanted them reinterred.

Scientists won and conducted several rounds of analysis on the bones. Based on the shape of the skull and chemical tests, lead researcher Doug Owsley of the Smithsonian Institution argued that the man was not Native American and might have come from the coast, not the Columbia Valley.

But two independent laboratories later conducted DNA tests that confirmed the man was most closely related to modern Native Americans.

Representatives from several tribes, who have regularly vistited the Burke to pay homage to The Ancient One, said earlier that they have plans for reburial on ancestral lands near the Columbia River.

The tribes that will take possession of the skeleton include the Confederated Tribes of the Umatilla Indian Reservation, the Confederated Tribes of the Colville Reservation, the Confederated Tribes and Bands of the Yakama Nation, the Nez Perce Tribe, and the Wanapum Band of Priest Rapids.
